hey, could i have another account registered with my friend's name. then ask her to upload wadeva stuff i need her to and stuff like that. is this counted as breaking the TOS?
No, I don't think this will count as breaking rules. Since you are creating in another member's name and you are helping her in setting up her own site, but the X10hosting crew will be along....and you will know for sure
If you need more space I think you should change your account to adEnhanced, as why waist his/her space/bandwidth, if they are hosting a site they'll need it.
